PDLIM7 and Epstein-Barr virus infection: Thus, differences in LMP1 expression do not explain why T2 EBV LCLs remain more lytic than T1 EBV LCLs (at least for the first few months in culture) but do suggest that there is considerably more selective pressure for LCLs with T2 EBV infection to express higher levels of LMP1 compared to lymphomas with T2 EBV infection in the CBH model.
